MANUFACTURE OF EMULSIONS AND SUBSTANCES FOR USE 'ILHEJREIN.

niasaee.

To all whom it may concern Be itknown that i, om Biionnn, r15... n,

chemist, a citizen of the Empire of Germany,

residing Frankfort-on-the-Main, Germany, have invented certain new and useful Improvements in the Manufacture of Emuh sions and Substances for Use Therein, of

which the following is a specification.

it is known that the power of the fats arylsulfonimids Under theterm emulsions and oils to; absorb water is improved by the addition of certain chemical substances.

By my invention particularly suitable substances for this purpose are the acidylcontaining an al phatic acidyl group and corresponding with the formula:

Ar.SQ .NM.Ac wherein Ar stands for aryl, Ac for aliphatic acidyl, and M for hydrogen, ammonium, a metal, etc. Such sulfommids are, for 1nstance, stearylbenzenesulfonimid or pal- -mityl-para-toluenesulfonimid; they possess the further advantage that they form salts with alkalis, alkaline earths and heavy metals. This latter property is of great value for the preparation of all sorts of emulsions for technical, pharmaceutical and medicinal purposes, particularly when using such emulsions for sprinkling therewith wool to be subsequently used for piece-dyed textile goods, because the emulsifying substance can be moreeasily removed by washing so that an uneven dyeing, cloudy appearance of the fabric, development of odor in the goods after they have been stored for some time, or th e like, is avoided.

I comprise in this specificationfemulsions of oils, fats, soaps, carbohydrates and their derivatives; furthermore, ointments, liniments or the like, with or without the additionof soap or the like.

The sodium salt of palmitylara-toluenesulfonimid may, for instance, e caused to react with CaCl,, AgNO or HgCl to form white salts, with C-uSO to form a slightly greenish salt, and with FeCl, to

form a light yellow salt. These new acidylaryl-sulfonimids are obtained by the action of halides of the higher fatty acids upon arylsulfonamids.

The halides of higher fat acids, such for instance as palmityl c orid, stearyl specification of Letters la'cent.

stance, those which are already employed in the preparation of other acid chlorids, the reaction is much smoother and pure prodnets are directly obtained. This new method has the further advantage that it renders it possible easily to distil 0E in a vacuum the necessary excess of thionyl chlorid, or the phosphorus oxychlorid produced during the reaction.

Among the acidyl-aryl-sulfonimids there where hitherto known only those containing aromatic acidyl groups, such for instance as and with the exception of the compound from of the higher fatty acids act upon the arylsulfonamlds without any by-reaction, the corresponding acidyl-aryl-sulfonimids being obtained in quantitative yield; a fact which;

could not at all be foreseen. As already stated, the said acidyl-aryl-sulfonimids yield salts when combined with alkalis, al-

kaline earths or heavy metals, a fact which is of particular importance for the purposes for which the products are intended. The new compounds are'distinguished from the hitherto known acidyl-aryl-sulfonimids by their aforesaid valuable properties, which consist in raising the melting point of oer-- tain fatty-acids, in rendering bases of ointments capable of better absorbing water, in particular suitability for washing-preparations and emulsions, and in rendenng phenols or the like soluble in water.

The following examples illustrate the invention 1. Manufacture of halides of the higher i fatty acids.

1. 28.4; kilos of commercial stearic acid are mixed with 30 kilos of carbon tetrachlorid and this mixture is heated on the water bath in a reflux apparatus with 20.8 kilos of phosphorus pentachlorid until ,there 1s no further formation of hydrochloric acid.

ular proportions of thionyl chlorid until the formation of hydrochloric acid ceases. The carbon tetrachlorid thus added is then distilled on the water-bath in a vacuum together with the excess of thionyl chlorid and the remaining traces of hydrochloric acid and thionyl chlorid are expelled by a further addition of carbon t6tI3.ChlOI1d.' ll. Prepramtioh of the addyZ-aryZ-sulfon .mz'ds.

3. 98 kilos of sodium benzenesulfonamid are heated in an oil-bath for about 1-2 hours at about 100 120f" C. with 152 kilos of stearic acid chlorid. When recrystallized from alcohol the .crude product melts at 104 C.

4. 85 kilos of .para-toluenesulfonamid are heated on the water-bath in presence of an indifierent solvent such, for instance, as

carbon tetrachlorid, with 137 kilos palmitic acid 'chlorid, until the evolution of hydroehloric acid; ceases. When crystallized from alcohol the product thus obtained melts at 100-102 C.

Ill. Preparations of ointments, Zim'ment s,

, g k I emulsions orthe like.

5. 5 kilos of Vaseline melting at 35 C. are mixed with 1 kilo of palmityl-paratoluenesulfonimid; the melting point is thus changed to C.

6. A mixture of 10 kilos of olive oil, and 1- kilo of stearyl-para-toluenesulfonimid to which 3 liters of water are added forms a stable white ointment.

7. @A mixture of 45 kilos of cod-liver oil "and 5 kilos of ammonium palmityl-paratoluenesulfonimid, ---t o which 50' liters of water are added yields a yellowish white em ulsion.

8. A mixture of kilos of ammonium palmityl-para-toluenesulfonimid and 12 kilos of soap of 60 per cent. strength isboiled with 200 liters of water, there are then added, while stirring, 30 kilos of carbon tetrachlorid and the whole is diluted with enough water to make 1000 liters of the composition, which forms a stable emulsion suitable for use. as a detergent.

9. A mixture of 6 kilos of potassium stearyl-benzene-sulfonimid and 12 kilos of a soap of 60 per cent. strength is boiled with 200 liters of water; there are then added, while stirring, 30 kilos of lubricating oil and the whole is diluted with enough water to make 1000 liters of the composition, which forms a white, stable emulsion suitable as a lubricant for boring tools.

10. A mixture of 6 kilos of sodium palmityl-para-toluenesulfonimid mixed with 12 kilos of a soap of 60 per cent. strength is boiled with 200 liters of water; there are then added, while stirring-4.0 kilos of olein and the whole is diluted with water to make .1000 liters of the composition, which forms a white mucilaginous emulsion suitable as a spinning oil. I

11. A mixture of 9 parts by weight of olive 'oil and 1 part by weight of calcium palmityl-para-toluenesulfonimid to which 3 parts by weight of water are added, forms a mucilaginous emulsion suitable as an ointment.

12. A mixture of 9 parts by weight of arachis oil and 1 part by weight of stearylpara-toluenesulfonimid of zinc to which 5 parts of water are added, is a stable yellow ish-white ointment.

Having now described I laim is As a new process the manufacture of emulsions, which consists in incorporating with the body tobe emulsified an acidyla'ryl-sulfonirmd of the general formula I Ar.SO,.NM.Ac

wherein Ar stands for aryl, M for H, NH, a metal, and Ac for an aliphatic acidyl.
